Neuronal signals conveying luminance contrast play a key role in nearly all aspects of perception, including depth perception, texture discrimination, and motion perception. Although much is known about the retinal mechanisms responsible for encoding

The structural and functional properties of the visual system are disrupted in mutant animals lacking the β2 subunit of the nicotinic acetylcholine receptor. In particular, eye-specific retinogeniculate projections do not develop normally in these m

Axon guidance cues contributing to the development of eye-specific visual projections to the lateral geniculate nucleus (LGN) have not previously been identified. Here we show that gradients of ephrin-As and their receptors (EphAs) direct retinal gan

Multilevel (ML) recording technology doubles the speed and capacity of standard digital versatile disc (DVD) writable and rewritable systems. Implemented with the addition of single chip or core to the standard drive architecture, ML technology doubl

Assessing the reliability of neuronal spike trains is fundamental to an understanding of the neural code. We measured the reproducibility of retinal responses to repeated visual stimuli. In both tiger salamander and rabbit, the retinal ganglion cells

Owing to the limited dynamic range of a neuron's output, neural circuits are faced with a trade-off between encoding the full range of their inputs and resolving gradations among those inputs. For example, the ambient light level varies daily over mo

Until recently there have been no convincing quantitative measurements on the rates of information transmission in real neurons. Here we review the theoretical basis for making such measurements, together with the data which demonstrate remarkably hi

Many sensory neurons code information about the sensory world in discrete spike trains. How much information is carried in sensory spike trains and how close are the information rates to fundamental limits imposed by the spiking statistics? By learni

We show how an overcomplete dictionary may be adapted to the statistics of natural images so as to provide a sparse representation of image content. When the degree of overcompleteness is low, the basis functions that emerge resemble those of Gabor w
